Soneil Spark Unveils Mobile BESS at RE+ 2026

Soneil Spark is set to unveil its Mobile Battery Energy Storage System (Mobile BESS) at RE+ 2026, scheduled for November 17–19 in Las Vegas. The company will showcase the portable, modular battery storage solution integrated into a towable trailer at booth W17059 in the West Hall.

Setup is as simple as tow, connect, power: the Mobile BESS works from day one, with no crane, no trenching and no utility wait.

That makes it a natural fit for a job site months away from permanent service, a film set or event that can’t tolerate generator noise and fumes, a utility crew restoring power after a storm, or a remote mine or farm beyond the grid’s reach. On sites that already run generators, the Mobile BESS syncs with them to cover peaks and start-up gaps, so the generators run fewer hours. Where diesel is restricted, it offers a quiet alternative.

Orders are open now, and standard configurations ship in about four weeks.

“Wherever your business goes, the power goes with it. Simply tow it where energy demand grows,” said Sonya Jain, CEO of Soneil Spark. “Start with one unit and add more as your needs change.”

Where containerized storage is built to be placed once, the Mobile BESS is built to be towed and to work in any weather:

Independent air suspension: engineered to minimize towing vibration, with 6–14″ of ground clearance and all-terrain tires for off-road sites
All-climate performance: −20 to +50 °C standard, or −35 to +50 °C (−31 to +122 °F) with the cold-weather kit
Safe on the move: automatic fire suppression at battery and trailer level; UL 1973, UN 38.3 and UL 1741, and designed to meet UL 9540A requirements
Monitored and backed by SLAs: LTE remote monitoring with real-time alerts and remote diagnostics, a 2-year warranty, 24/7 technical support and service-level agreement (SLA) options for each use case

The Mobile BESS is built for generator and equipment rental, construction, emergency and backup power, utilities, electrical contractors, events, film and entertainment, and off-grid sites such as mining and agriculture. A hybrid option adds EV charging.
